Yuav Ua Li Cas Npaus Fais Kua Dej Kub Tua Hluav Taws?
Hluav taws kub hnyav vim hais tias muaj plaub yam tam sim no. Cov ntsiab lus no yog cua sov, roj, cua (pa) thiab cov tshuaj lom neeg. Raws li muaj xwm txheej yog tias muaj ib lub ntsiab lus raug muab tshem tawm / raug cuam tshuam nrog, qhov hluav taws kub tua. Hluav taws ntaus ua npuas ncauj tsis cuam tshuam rau cov tshuaj lom neeg cov tshuaj tiv thaiv. Ua npuas ncauj ua haujlwm hauv qab no:
Cov npuas dej npau dej ntxig nplaim hluav taws kub.
Daim npog npuav cais tawm cov nplaim taws / qhov hluav taws kub tawm ntawm cov roj av.
Qhov ua npuas dej ua rau cov roj thiab tej qhov chaw uas nyob ib sab npuas txias.
Npog daim npog tus suppresses tso tawm ntawm cov hluav taws uas muaj peev xwm tuaj yeem sib tov nrog huab cua.
Nram qab no yog ib daim ntawv teev cov khoom siv foam concentrates uas yog hom tshaj plaws:
Aqueous zaj duab xis ua foam (AFFF)
Cawv Resistant (AR-AFFF)
Khoom siv hluavtaws - nruab nrab lossis siab loj hom (xab npum)
Chav kawm "A" Ua Npuas Ncauj Ua Ntej
Wetting Agent
Fluoroprotein
Protein
Zaj Dab Tsi Ua Duab Tsom Fluoroprotein (FFFP)
COV NTAUB NTAWV TSIS TXAUS SIAB TXOJ KEV UA NEEG UA HAUJ LWM (AFFF):
Muaj nyob rau hauv 1%, 3% lossis 6% hom concentrate. AFFF xav txog kev sib xyaw ua ke ntawm cov roj carbon dioxide thiab fluorochemical deg dej ntau. Nws ua ib qho yeeb yaj kiab vapor-sealing aqueous uas kis sai sai dua cov roj ntws los muab kev tswj ceev thiab tua hluav taws xob.
■ Ua yeeb yaj kiab tsim kom muaj nplaim taws ceev thiab thawb lub nplhaib.
■ Kub nyhiab thiab tiv thaiv kev kub ntxhov.
■ Ua npuas ncauj pam txaj muag thaum neeg raug mob los ntawm cov neeg ua haujlwm lossis khoom siv.
AFFF 1% yuav tsum muab siv rau 1% feem pua tshuaj (1 feem ntau sab hauv 99 ntu dej) hauv brackish, fresh or sea water. Nws kuj tseem yuav muab khaws cia ua ib qho tshuaj rau hauv dej tshiab.
AFFF 3% yuav tsum raug siv ntawm 3% feem ntau cov dej (3 feem ntau sab nrauv hauv 97 seem ntawm dej) hauv brackish, fresh or sea water. Nws kuj tseem yuav muab khaws cia ua ib qho tshuaj rau hauv dej tshiab.
AFFF 6% yuav tsum muab siv rau 6% feem pua tshuaj (6 feem ntau feeb hauv 94 seem ntawm dej) hauv brackish, fresh or sea water. Nws kuj tseem yuav muab khaws cia ua ib qho tshuaj rau hauv dej tshiab.
FFFP FILM HAIS TXOG FLUOROPROTEIN (FFFP):
Zoo nkaus li cov FluoroProtein (FP) ua npuas ncauj ntau Cov Yeeb Yaj Saub Ua Fluoroprotein ntau yog tsim los ntawm kev ua kom muaj protein ntau ntau thiab yog qhov zoo rau cov tua hluav taws thiab ruaj rau cov hluav taws kub kua roj. FFFP foams muaj qhov kom zoo dua qub ntxiv uas lawv tuaj yeem siv tau los ntawm lawv cov peev xwm ntawm kev ua yeeb yam. Lub hauv paus ntawm lub hauv paus muab ib lub hnab khov cohesive npog nrog siab tiv thaiv kom sov sai sai, txias, thiab ua ke cov kev txaus ntshai, thiab cov yeeb yaj duab tsim muaj peev xwm coj tau sai knockdown.
Cov duab yeeb yaj kiab Fluoroprotein foams yog qhov zoo tshaj plaws rau kev siv cov xwm txheej uas muaj kev kub ntxhov (xws li cov roj av kerosene, cov roj crude, roj, thiab roj hluav taws xob) uas yog khaws, ua tiav, los yog xa mus. Lawv siv ntau zaus rau Cov Kev Hloov Tawm Huab Cua hauv cov chaw dav dav thoob hauv thoob ntiaj teb thiab cov tub rog hauv cov tub rog qhov chaw tua hluav taws sai thiab kev nyab xeeb tom qab muaj kev txwv ntau heev.
■ Ua yeeb yaj kiab tsim kom muaj nplaim taws ceev thiab thawb lub nplhaib.
■ Kev ruaj ntseg thiab ruaj khov ntev ntev rau cov hluav taws kub hnyiab thiab hluav taws kub tom qab hluav taws.
■ Tsis pub tshuaj-dawb rau cov neeg ua haujlwm tsis zoo rau roj tuaj tos.
■ Ua npuas ncauj pam rov qab thaum lub ruptured los ntawm cov neeg ua haujlwm lossis khoom siv.
■ Txo cov nqi qis, txo qis nqi, nyiaj txee rau lub neej, thiab qis siv qis ua ke los muab cov nqi qis tshaj plaws.
